CASSETTE FOR INSTALLATION OF OPTOELECTRONIC EQUIPMENT IN THE UNDERWATER COUPLING HOUSING Russian patent published in 2022 - IPC G02B6/36 G02B6/50 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of marine instrumentation and can be used in the design of an underwater coupling to accommodate optoelectronic equipment in it. The claimed cassette for installing optoelectronic equipment in the housing of the underwater coupling is a spatial structure, the side faces of which are formed by four lodgements extended along the axis of the cassette, while all lodgements are made the same and installed with the convex side to the housing, and the flat side inside the cassette, and on the flat sides of the lodgements it is possible to fix one or more boards with screws with nodes of optoelectronic equipment and heat removing radiators. Each of the ends of the cassette consists of two half-rings with bolt holes for fixing the ends of the lodgements, while each half-ring from one edge has a protruding eyelet offset to the outer edge of the half-ring and has a bolt hole for connecting the two half-rings to each other, and from the other edge a groove for installing a sliding mechanism. In this case, the sliding mechanism is a thrust fork with a bolt hole for rigid fixation of the fork in the groove on one half-ring, a release bolt installed in the groove on the opposite half-ring, and a release nut installed on the release bolt. The length of the base of the eyelet is less than the length of the edge of the half-ring. The width of the eyelet is half the width of the half-ring.

EFFECT: reduction in the time of installation/removal of the cassette from the coupling housing and access to the equipment installed in the cassette.
